Some thoughts - guessing you will have a car

Sonesta in Maho - close to airport, AI, but with a summer rate who cares if you miss some meals and no foraging for food and drink if you are a 1st timer

Horny Toad - no recent info, but on beach, inexpensive

These 2 options put you close to provisioning, charter and resto / bars and airport if you hae to pick up any incoming crew

Could try Grand Case area or Orient - maybe La Playa

Let us know what you choose
